SPECIFICATION forming part of Letters Patent No.'302,188, dated July 15, 1884.

Application filed November 12. 1883. (No m del.)

To all whom, it may concern.-

Be it knov' n that I, JAMES H. Bnnenss, of Maiden, in the county of Middlesex and State of Massachusetts, a citizen of the United States, have invented a certain new and useful 1mprovement in Lubricators, of which the following is a full, clear, and exact description, reference being bad to the accompanying drawings, forming a part of this specification, in explaining its nature, in which Figure 1 is a vertical section of a lubricator containing my improvement. Fig. 2 is a horizontal section on the line 1 of Fig. 1. Fig. 3 is a vertical section of a lubricator, showing a water-chamber in the upper part of the oilcup. Fig. 4 is a vertical section of the sightfeed chamber.

The invention consists, especially, in a lubricator having a sight-feed chamber of peculiar shape and arrangement upon the side of p the oil'chamber, at or near its top, and into passage Z2 with the sage enters the which sight-feed chamber drops of water from a hydrostatic column are allowed to pass.

Referring to the drawings, A represents the oil-cup. a is the chamber therein. B is the sight-feed chamber, which is connected by the oil-chamber a. This pasoil-chamber at or near its upper end. The sight-feed chamber B preferably is made or formed, as shown in Figs. 1 and 2, of a cylindrical shape, and its ends are closed by the glass disks 1), which are held in place against shoulders upon the cylinders by means of the hollow nuts b which screw into the ends of theeylinder. These disks may be of the same thickness, or they may be formed as represented in Fig. 4, so that a portion shall extend into the cylinder beyond the shoulder. Between these disks is the sight-feed chamber, and, preferably, it should be narrow, in order that the drops of water that pass through it may be readily observable. A nozzle, 0, extends into the sight-feed chamber, and it is arranged at the lower end of a water-supply pipe. This pipe may be a long condensingpipe, as represented in Fig. 1, or it may be a short connecting-pipe, as represented at c,

Fig. 3, connecting the nozzle with a chamber, 0, in the upper part of the casing A, which go is adapted to be filled with water from the 0011- densing-pipe c, or in any other desirable way, the only difference between the constructions shown in Figs. 1 and 3 being that in the con} struction shown in Fig. 3 the water-chamber is interposed between the two sections of the ply with the nozzle 0. shaped substantially has extending through it a hole,

as shown in Fig. 3, and

oil is introduced to the oil-chamber.

syphon tube, 0, with the steam-supply pipe, and this tube may have a valve, 0", for limiting or controlling the supply of steam.

Extending from the side of the oil-chainber and also fills the sight-feed chamber. The water-chamber is also filled with water either by condensation of steamer otherwise, and the cock is then turned sufiiciently to allow an escape of 'oil froni the reservoir. The water will immediately drop from the end of the nozzle 0 in the sight-feed chamber through the oil therein, and will enter the passage b and fall to the bottom of the cup, lifting or displacing alike quantity of 0il,and as the sightfeed chamber is narrow the passage of the drops of water therethrough can be readily seen. If the oilis light, the drops of water are of a white sparkling appearance, and if the oil is dark, the drops show red; but in either event they are very clearly shown. It is preferable to make the passage connecting the sight-feed chamber with the chamber in the oil-cup somewhat inclined from the bottom of the sight-feed chamber to the cup, in order that the water may freely escape therefrom.

It will be obvious that as the sight-feed chamber is located at or near the top of the oil-chamber, it will continue filled with oil un- In operation the oil'chainber is filled with oil, and it overflows through the passage 1),

pipe which connects the source of water-sup} The said chamber 0 is 0', adapted to be closed by a screw-plug, 0, through which" The wa ter'chamber, which may also be a condensingchamber, is connected by means of a bent or y near the top, is the oil-escape passage D, which 5 of dropsoi water through til very nearly all the oil has been fed from the oil-chamber and its place taken by the water.

By arranging the sight-feed chamber as de 5 scribed, two or three desirable results are obtained: first, the construction is simple and cheap; second, the sight-feed chamber is so placed that for locomotive-cups especially the feed is in a position to be seen by both the engineer and fireman while they are in their ordinary positions in the cab; third, the method of its operation is very simple and easily understood; fourth, the sight-feed glasses are entirely protected fronrany danger of break- I 5 age and are easily removable, and can therefore be cleansed as often without any trouble.

It 'will be noticed that the sight-feed chamber is made very narrow, in order to obtain a thin body ofoil, so that the passage ofeach drop of water through it may be distinctly Visible from both sides of the chamber. It will also be seen that the sightfeed chamber is so located that it permits the feed or the passage it to be observed as may be necessary equally well from both It will benotieed that because the body of oil is thin, and because it receives light from both sides of the chamber, the oil and even drops of water that pass through it are illuminated, even the darkest oil becoming sufliciently clear to show the passage of the drops of water through it with very great distinctness. Moreover, the passage of the drops through the chamber is so slow that often more than one or two are visible at thesame The sight-feed also indicates when the ti m e.

sides of the chamber.

cup is empty, because the chamber will show water when the oil has been very nearly expelled from the lubricator by the rise of the i water. Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States I 1. A lubricator consisting of an oil-cup having the chamber a, the oil-escape passage D, and'the sight-feed chamber 13, connected with chamber a by a single passage, 6, only, upon I the side of the oil-cup at or near its top, conneeted with said chamber by the passage 1), k

I and having a water-supply passage opening into the same. all substantially as and for the purposes described.

2. A lubricator having an oil-chamber and a thin disleshaped sight-feed chamber glazed at each end, at the side, and near the top of the oil chamber, which sight feed chamber is l side passage only, and a nozzle in the top of the sight-feed chamber through which water is dropped into said sight-feed chamber nearto each glass thereof, substantially as described. 3. In a lubricator, the oil-cup A, having I laterally connected therewith by passage 6, 1' near the top of said oil-cup and below the oi]- delivery passage, a thin disleshaped sight I feed chamber. B, glazed at opposite ends, into i the top of which sight-feed chamber. between the glasses, is inserted the water-inlet 0, substantially as described.
